Intshayelelo yovavanyo lwe-hydrostatic yetanki yokugcina i-LNG
Umhla: Nov 29, 2019
Xa sifuna ukuqinisekisa ukuba umgangatho wemveliso ye-CryOgenic Lng, kufuneka sithathe amanyathelo asebenzayo. Ke maliphi amanyathelo asebenza ngakumbi kwiitanki zokugcina i-LNG? Makhe siqwalasele uvavanyo loxinzelelo lwendlela elungileyo-hydraulic.
Ukuqinisekisa umgangatho wemveliso weetanki zokugcina i-LNG, uvavanyo lwe-hydrostatic luyafuneka:
1. Chaza iitanki ze-lng ezifuna ukuba zivavanywe nge-hydrostattically, kuba iitanki ze-lng zezinto ezahlukeneyo zineendlela ezahlukeneyo ze-hyddraulic;
2. Okwesibini, xaItanki yokugcina i-LNGigqityiwe ukuveliswa, kufuneka kuvavanywe uxinzelelo lwamanzi. Ukuba kukho iimfuno zovavanyo olukhutshelweyo, ke amanzi acocekileyo kufuneka asetyenziselwe uvavanyo lwamanzi;
3. Xa usenza uvavanyo loxinzelelo, unokuqala ukwenza uvavanyo oluneenkcukacha kwiNkqubo yovavanyo yoXinzelelo. IYIXHONO YOVAVANYA UKUTHENGA KWE-STRICRY NOPHANDO LWE-PARTALS System nganye, nokuba ichanekile na ekufakweni;
4. Lungisa iItanki le-lngOko kufuna uvavanyo lwamanzi lwengcinezelo kunye nokugcwaliswa kwamanzi. Ukuze kusetyenzwe i-voltage, kuthatha malunga nemizuzu engama-30, emva koko ujonge ukungcungcutheka kunye nokuvuza. Ukuba akukho meko ingaqhelekanga, ke inokwenziwa ngoxinzelelo, kodwa ithatha malunga nemizuzu engama-30, emva koko ihlolwe indawo yokutywina, ubukhulu becala kubandakanya isikhundla somthungo we-weld, kunye nemeko yokuvuza.
